Small pSLC by current cheap drive standards, unless maybe it’s a 128 GB. Folding should be at 3.5 speeds, maybe getting close to 1 GB/s depending how the shopping goes, but it’s definitely buyer beware.
I’ve had decent luck with what Lenovo’s decided to put for OEM drives (WD and SK Hynix TLC) but paying their upcharge’s certainly quite low in my priorities. Worst I’ve come across in the past few years was an order that happened off my watch where they paid the upcharge for 1 TB and then Dell put a 2.5 SATA III SSD instead of using the PCIe 4.0 x4 M.2 on the motherboard.
